Baosteel non-oriented electrical steel series B20AV, B25AV, and B35A is specifically developed for high-RPM electric vehicle (EV) traction motors and precision industrial servos. Isotropic magnetic response and ultra-thin gauges from 0.20 mm suppress high-frequency eddy current losses up to 1000 Hz.
OCTG Seamless Casing and Tubing with BG Premium Connections
Baosteel OCTG seamless casing and tubing strings are engineered for deep, extended-reach wells operating in severe sour environments containing H2S and CO2.
Proprietary premium connections BGT1 and BG-HD feature gas-tight metal-to-metal seals and reverse-angle torque shoulders to resist extreme bursting pressures and severe bending fatigue in directional drilling.
Ordering parameters: OD, wall thickness, steel grade (BG90SS, 13Cr, Super 13Cr), and BG connection profile.
Baosteel 3rd-generation automotive sheet steels QP980, QP1180, and DP800/1000 offer unmatched balance between strength and formability for crash-absorbing vehicle body structures.
Boron-alloyed press hardening steels PHS1500 and PHS2000 reach tensile strengths up to 2000 MPa during in-die water quench, providing impenetrable structural cage protection.
Cryogenic 9% Ni Heavy Plate B9Ni for LNG Tanks & B-HARD Wear Plates
Baosteel 9% Ni alloyed heavy plate B9Ni (ASTM A553) is specifically produced for cryogenic containment vessels and liquefied natural gas (LNG) storage tanks operating down to -162 °C. High fracture toughness prevents brittle crack propagation.
Abrasion-resistant B-HARD plates (400–500 HBW) deliver extended operating life in severe mining and earthmoving applications.
Baowu Super-Galum (ZM) alloy-coated coils feature an optimized eutectic coating of zinc, 11% aluminum, and 3% magnesium. ZM metallurgy delivers more than 6-fold corrosion endurance over standard galvanized steel and self-heals cut edges in aggressive atmospheres.
Pre-painted coils (PPGI/PPGL) with PVDF fluoropolymer resins maintain color integrity and UV barrier up to 40 years.
Selection criteria: coating mass (g/m²), substrate thickness (0.4–3.0 mm), and topcoat polymer resin (PVDF, HDP).
Baosteel electrolytic tinplate (ETP) and tin-free steel (TFS/ECCS) coils deliver world-class packaging solutions for sanitary food cans, beverage closures, Easy-Open ends, and high-pressure aerosol containers.
Precision single-reduced (SR) and double-reduced (DR-8, DR-9) tempers ensure excellent deep-draw formability, lacquer adhesion, and complete protection against aggressive food acids.
Ordering parameters: tin coating mass (differential/equal), temper rating (T-1 to DR-9), and thickness (0.14–0.40 mm).
Baowu Heavy Machinery Mill Rolls, Chocks & Continuous Caster Spares
Baosteel Engineering & Technology (Baowu Heavy Machinery) manufactures genuine hot- and cold-rolling work rolls, back-up rolls, forged steel chocks, hydraulic gap control (HGC) cylinders, and continuous slab caster roller segments.
Heavy components feature superior spall resistance, core toughness, and dimensional stability under severe cyclical rolling loads.
Selection criteria: roll drawing code, barrel diameter, hardness rating (HSD), alloy composition, and mill stand type.
Ordering Criteria for Baosteel Metallurgy
Designation grade or equivalent specification (ASTM, EN, DIN, ISO), dimensional geometry (strip thickness, coil slit width, pipe outer diameter and wall thickness), order tonnage, surface finish class, mechanical test protocols, and protective metallic or organic coating requirements.
Baowu Mill Rolls, Heavy Bearing Chocks & Caster Spares
We supply genuine forged and centrifugal-cast work rolls, back-up rolls, structural bearing chocks, hydraulic gap control (HGC) cylinders, and slab guide assemblies from Baosteel Engineering & Technology based on equipment drawings and operating parameters.
Metallurgy and Domain Refinement in Baosteel GOES Electrical Steel
China Baowu Steel Group is a world leader in high-performance electrical steels. For ultra-high voltage (UHV) transformer cores, Baosteel produces Hi-B grain-oriented grades featuring laser domain refinement. 70 W/kg.
Thin non-oriented grades (B20AV) deliver low high-frequency core loss and 550 MPa tensile resistance for EV traction motors spinning up to 20,000 RPM. Rigorous stacking factor verification guarantees optimal magnetic induction in high-power substation designs.
Performance and Integrity of OCTG Seamless Tubulars with BG Threads
3 to 508 mm compliant with API Spec 5CT. For severe environments with hydrogen sulfide and CO2, Baosteel supplies proprietary sour service grades BG90SS, 13Cr, Super 13Cr, and alloy BG2535.
BGT1 and BG-HD premium threaded connections with metal-to-metal spherical seals guarantee 100% gas-tight integrity under pressures exceeding 100 MPa. Full-length ultrasonic testing ensures zero lamellar defects in critical offshore downhole operations.
3rd-Generation QP Steels and Boron-Alloyed Press Hardening Steels
Automotive light-weighting relies on Baosteel QP980 and QP1180 steels, achieving 15–25% weight reduction while preserving formability via deformation-induced martensitic transformation (TRIP effect).
For occupant protection zones, Baosteel supplies boron-alloyed hot stamping steels PHS1500 and PHS2000, which reach 1500–2000 MPa tensile strength after in-die quench with zero geometric spring-back. This superior dimensional consistency streamlines automated robotic body-in-white welding lines.
Cryogenic 9% Ni Plate B9Ni for Liquefied Natural Gas Containment
For onshore LNG storage tanks and membrane fuel containment, Baosteel produces B9Ni heavy plate (ASTM A553). 3 mm CTOD crack-tip opening at -196 °C, eliminating risks of catastrophic brittle failure under cryogenic storage pressures.
Class 1 ultrasonic inspection verifies complete internal volumetric homogeneity.
Baowu Super-Galum coated coils utilize a ternary zinc, 11% aluminum, and 3% magnesium alloy (ZM) that outperforms traditional hot-dip galvanizing by more than 6 times in salt-fog exposure. Magnesium promotes dense simonkolleite films that self-heal cut edges and micro-scratches.
ZM coils provide superior longevity in photovoltaic mounting trackers, harsh agricultural shelters, and marine climates. Pre-painted PVDF finishes maintain architectural aesthetics up to four decades.
High-Integrity Sanitary Packaging: ETP Tinplate and TFS Coils
For sanitary food canning and aerosol manufacturing, Baosteel produces single- and double-reduced tinplate (up to DR-9 temper) with differential tin plating.
Tin-free steel (TFS/ECCS) provides excellent polymer film and lacquer adhesion, preventing sub-surface corrosion during retort food autoclaving at 120–135 °C. Uniform surface microroughness facilitates high-speed multi-color printing and lithography.
